解説（安達）
　永長氏の画像では、朝霧が良く出ている。クロニウム(Mare Chronuim;200W,
-60)がはっきりと見えてきた。また、北半球ではアエテリア(Aetheria;240W,
+45)の暗斑も確認できる。目立った変化はないようだ。
Ralf Vandebergh氏の観測ではオフィール(Ophir;70W,-5)が明るく記録されてい
るが、この部分はもともと明るい地域である。しかし、同じ場所にダストの発生
した可能性もあり、注意を要する。(reported by 3 observers)

In the image of Einaga, the morning mist has occurred well. Mare
Chronuim (200W,-60) has come into view clearly. Moreover, dark section
of Aetheria (240W,+45) can be confirmed in the northern hemisphere.
There seems to be no remarkable change.
This part is a bright originally region though Ophir (70W,-5) is
brightly recorded in the observation of Ralf Vandebergh. However, there
is a possibility that dust is generated in the same place, too and
attention is required. (reported by 3 observers)

今朝は天頂付近はずーっと晴れているのですが、火星の方向はずーっと雲がかかりっぱなしでした。
４時を回ってからはほとんど観測不能となってしまいました。
・大きな変化はなさそうです。

Attached are my first Mars observations of this season.Taken June 27 in near-infrared.
We see Mare Erythraeum,Chryse,Argyre,Niliacus Lacus etc.Note also the dark polar collor already.
It was a good feeling to see my scope pointed higher in the sky again,after the
poor altitude season of Jupiter.




Although I couldn't take good blue images for a color composite in the better seeing at the high 
altitude against the blue sky,some time earlier I had some,however.Because Mars was a bit lower now,
the seeing was not as good as on the bw images,but now I could create a color composite.
Here is the result,with a resolution from 0.1´´/pixel .IR-sG-B observation.


 I have attached another IR-sG-B image taken on june 27,now at 04:59 UTC.


Attached is a special High Contrast processing of one of my June 27 observations,
showing especially the southern polar collar very well.

Here are some additional images from june 27,with different processings.
I have arrowed a kind of spot within the Ganges/Condor region.


  Here is another image from my June 27 Mars observing session.
